Patent GB-971845-A (GB)
Title: A process for the production of sheet materials from polyamide fibres
IPC: D21H/
Filed: 1963-01-25
Abstract: Sheet materials are made from polyamide fibres by treating the fibres with certain water-soluble polymers, dispersing the treated fibres in water, casting the dispersion to form a web, dehydrating, drying and consolidating the product.  The polymers are of monomers comprising double bonds, have a molecular weight of at least 1500, contain acidly reacting functional groups and are substantively absorbed on polyamides at a p H below 4.  The polymers may contain aromatic nuclei and free carboxyl or sulphonic groups, e.g. polystyrene-sulphonic acid polyvinylsulphonic acid or a copolymer of styrene and an unsaturated acid or anhydride such as maleic acid or anhydride fumaric acid, acrylic acid or methacrylic acid.  The fibres may be dried after treatment with the polymer and before dispersion in water.  The products can be calendered hot or cold, or sprayed in a dry condition with impregnating agents or bonding resins, or p drawn through solutions or emulsions of such materials, e.g. a copolyamide.  They can be consolidated by heat and pressure, when they contain a proportion of polyamide fibres which have a lower melting point than the other fibres, using a temperature slightly above the melting point of the fibres of lower melting point.  In Example 1, polycaprolactam is spun through a slit nozzle, the filaments are formed into a tow, stretched and drawn through an aqueous solution of a copolymer of styrene and maleic anhydride, centrifuged, cut to a length of 6 mm, dispersed in water, deposited on the screen of a paper-making machine and dried.  The resultant web is then passed through a methanolic solution of a copolyamide made from hexamethylenediamine adipic acid and caprolactam, squeezed, dried and calendered.  In Examples 2 and 3 polycaprolactam is spun to form multifilar filaments, which are formed into a tow, stretched and cut to a length of 6 mm.  The staple fibres are stirred into a 5% solution of polystyrene sulphonic (Example 2) or polyvinylsulphonic acid (Example 3) and centrifuged.  In Example 2, the so-treated fibres are dispersed in water together with staple fibres of the copolyamide of Example 1, made into a web as in Example 1 and consolidated by calendering at 170 DEG C., melting point of the copolyamide.  In Example 3, the treated fibres are sheeted-out by themselves, and the resultant sheet drawn through an aqueous dispersion of melamine-formaldehyde, dried and calendered. Specification 868,651 is referred to.

Title: Commutator segments
Inventor: DIXON DOUGLAS LESLIE
IPC: H01R39/02
Filed: 1962-01-29
Abstract: 1,032,627. Making commutator segments; brazing. MORGANITE CARBON Ltd. April 25, 1963 [Jan. 29, 1962], No. 3337/62. Headings B3A and B3R. [Also in Division H2] A commutator segment comprises a steel body to which is brazed a layer of copper or copper based alloy to provide the operative face of the segment. The electrical conductivity of the copper material is lower than that previously used in commutator construction; suitable materials are deoxydized copper, cupro-nickel, " Monel " (Registered Trade Mark) metal, gun metals and phosphor bronze. If a greater surface hardness is required, a precipitation hardenable copper alloy may be used. A flux free brazing process is employed to join the two materials using a copper-silver eutectic as brazing alloy and the process is carried out in a moisture-free reducing atmosphere.

Abstract: 122,531. Carr, F. March 2, 1918. Animal traps. - A mole trap comprises two wire loops 3 fixed to a movable plate 1 and passing through a lower plate 2 to which is fastened an arched frame 5 supporting a spring 7 which is connected to a pawl 8 fixed to the plate 1. The shank of the pawl 8 passes through the plate 1 and ends in a laterally projecting arm 9. The trigger - plate 11 is pivoted in lugs 13 in the plate 2 and has an arm 14 ending in a laterally projecting part 15. The shapes of the arms 9, 15 are shown in Fig. 5. The trap is set by pushing down the plate 1 until the arm 9 pushes aside the arm 15 and passes down into a gap 16 in the trigger-plate 11. The trigger-plate swings back into its vertical position and thus brings the arm 15 over the arm 9. When downward pressure on the plate 1 is relaxed, the spring 7 causes the rounded upper part of the arm 9 to engage the rounded lower part of the arm 15. The lower part of the trigger may be embedded in a piece of stick. According to the Provisional Specification, the pawl and trigger arms may be duplicated.
